A simpler procedure for the routine measurement of methanol (MeOH) in house hold aerosol commodities was studied by the microdiffusion analysis. MeOH in the aerosols was converted to formaldehyde (HCHO) by potassium permanganate in an outer ring of Conway microdiffusion cells. The HCHO is absorbed in 0.1% methylbenzothiazolinonehydrazone (MBTH) solution of a center portion by means of diffusion in the cells standing for 4 h. at 40℃. To the solution of the center portion is added 1 ml of 5% ferric ammonium sulfate solution for color development. This procedure is available in screening of many samples examined for MeOH comparing the colors between the tested and standard solution. The samples positive toward MeOH are further examined by gas chromatography. A minimum amount of MeOH detectable by this method was 0.1 mg/g (sample).
